UNITED STATES PATENT onerous THOMAS E. TURNER, 0F SPRINGFIELD, OHIO, ASSIG-NOR TO INTERNATIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.

HAY-PRESS.

Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed. February 15, 1909. Serial No. 477,874.

To all whom it may concern:

Be it known that I, THOMAS E. TURNER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Hay-Presses, of which the following is a specification.

My invention relates to hay presses, andin particular to improvements upon the construction of the toggle mechanism forming part of the plunger actuating means, as shown in Patent No. 836,653, November 20, 1906, Frank A. Ryther, and is designed to more effectively guide the presser head as it is caused to move forward and backward in the press chamber, and it consists in an improved construction of the guide block forming part of the toggle mechanism, and in means for more rigidly connecting the stem that operates in the guide block with the presser head, shown in the acco1npanying drawing, in which- Figure 1 represents a side elevation of part of ahay press having my invention forming a part thereof; Fig. 2 is a partial cross section of Fig. 1 along the line AB thereof; Fig. 3 is a detail drawing, partly in section, illustrating the construction of the guide block and the manner of its operation in connection with the presser head stem; and Fig. 4 is a detached detail drawing representing a side elevation of the" toggle mechanism in one of its operative positions.

Like reference characters designate the same part-s throughout the several Views.

1 designates the frame of the press; 2 the press chamber in the rear end thereof, and 3 the bale chamber. The bottom of the frame includes corner angle bars 4 and centrally arranged angle bars 5, having their upper horizontal legs spaced apart in a manner to form a longitudinal slot 6, a plate 7 and angle bars 8, which are connected with and support the bars 4 and 5.

The presser head consists of a single flat plate 9, having secured to its lower corners lugs 10, having studs upon which are journaled rollers 11. At the center of the plate is secured a pair of ears 12 that receive between them the forward end of a plunger bar 13, and 14 designates a pin that pivotally connects the bar with the ears. Below the plunger, and near the bottom of the plate, is rigidly secured the forward end of a rearwardly projecting stem 15, having its rear end connected with the upper edge of the plate by means of a rigid brace member 16, the stem and the brace forming, with the plate, a triangle, of which the latter is the base.

17 designates a shield, having its forward end secured to the presser plate and its rear end supported by means of a bar 18, having its upper end secured to the shield 17 and its lower end to the brace member 16.

19 designates toggle bars having their lower ends pivotally connected with the frame 1, and their upper ends with the rear end of the plunger bar 13 in a manner forming a toggle connection between the plunger bar and press frame. A draw bar 20 extends forwardly beneath the press frame, having its rear end pivotally connected with the upper ends of the toggle bars 19 and the rear end of the plunger bar by means of links 21. The rear end of the draw bar is turned upwardly, and to its upturned end is secured a guide block 22, including asleeve portion 23, having at opposite ends thereof, and upon its upper and lower sides, ear portions 24:, between which are journaled antifriction rollers 25, having concave peripheries adapted to contact with the stem 15 that is received by the sleeve portion 23 in a manner to relieve the friction of the operative parts and prevent the sleeve from binding upon the stem durin the operation of the machine. The guide block is provided with oppositely arranged boss portions 26 upon its lower side that are adapted to receive between them the upturned end of the draw bar, and 27 represents a pin passing through the bosses and bar and having journaled upon their opposite ends rollers 28 that roll upon the upper surfaces of frame members 5 upon opposite sides of the slot 6, and 29 represents a pin passing transversely through the draw bar below the horizontal legs of the frame members 5, and 30 represents rollers journaled upon opposite ends of the pin and adapted to rollupon the lower surface of said legs.

In operation, the guide block acts a sliding support for the stem 15.

What I claim as my invention, and desire to secure by Letters Patent, is:

1. A hay press including, in combination, a press frame, a presser head, a toggle mechanism connecting said head with said frame, a draw bar connected with said toggle mechanisni, a guide block secured to said draw bar, a rearwardly projecting stein secured to said head near its lower edge and slidably receivedby said guide block, and a supporting brace having its forward end secured to the up'peredge of said head and its rear end secured to the rear end of said stein.

QI'A hay press including, in combination,

a press frame, a presser head, a toggle mechanism connecting said head with said frame, a draw bar connected with said toggle mechanism, a guide block secured to said draw bar, a rearwardly projecting stem secured to said head near its lower edge, asupportsleeve portion adapted to receive said stein in a slidable manner, and oppositely dis- 20 posed rollers journaled at opposite ends of said sleeve and adapted to engage with the upper and lower sides of said stein.

THOMAS E. TURNER.
